The Research of Measurement and Control System for Civil Aircraft Fire Laboratory

To meet the high-precision, real-time, and multi-task measurement and control requirements of the fire laboratory, a kind of measurement and control system based on Labview is designed. The measurement and control system of fire laboratory is composed of acquisition testing, fire extinguishing agent concentration testing, avionics simulation, laboratory power supply simulation, laboratory surveillance, total control table. This paper puts forward the design scheme of the whole system, and each functional module is introduced. The software of measurement and control using Labview greatly improves the operating efficiency of the measurement and control system.The reasonable configuration of Labview real-time engine makes the task cycle of the measurement and control system achieve millisecond level, which improves the real-time performance of the system. This system has the features of multi-function, high precision, good real-time performance, stable operation, and friendly interface,which can be satisfy measurement and control requirements of the fire test. The system has a good application prospect, which can be widely applied in all kinds of tests.
